TABLE-LEAF SUPPORT.

SPECIFICATIQN forming part of Letters Patent No. 335,265, dated February2, 1886.

Application filed June 13, 1885.

To all whom it may concern.-

Be it known that I, IRA \VINANS, of the city of Rochester, in the countyof Monroe and State ofNew York,have invented a certain new and usefulImprovement in Table-Leaf Supports; and I do hereby declare that thefollowing is a full, clear, and exact description ofthe same, referencebeing had to the accompany ing drawings, in which Figure] is a sideelevation showing the de vice applied to a table and the leaf extended.Fig. 2 is a similar view with the leaf lowered. Fig. 3 is a perspectiveview of the attachment with aportion broken away. Fig. I is a section inlineXX of Fig. 3. Fig. 5 is aplan view of Fig. 4, the parts beingseparated. Fig. 6 is a perspective view of lug for supporting the end ofthe leaf-support.

Myimprovement relates to table-leaf supports in which two jointed armsare used to hold the leaf extended, and which fold compactly when theleaf is lowered.

Theinvention consists in the combination of the arms and a hinged brace,one of the arms being slotted, and the brace having a crosshead thatslides in the slots, all as hereinafter described.

In the drawings, Ashows the tableleaf, and B a portion of the frame, towhich the leaf is My improvement is as follows:

C and D are two arms, pivoted at the outer ends to theleaf and frameandin the center to each other. The outer ends of the arms have rest andturn in socketed bearings c c. The outer arm, 0, is broadened in itscentral part both horizontally and vertically, and has in its top a longslot, (1, and in its sides two long slots, At its lower end it alsohastwo forked arms, 5 that form the knuckle, and a cross-bar, k, thatconnects them a little distance back from the end. The inner end of thearm D has a head, 70, that fits between the forks, and a slot, 1,through which passes the pivot m, that connects the parts, and also arightangled hook, p, which extends over and past the cross-bar h, and

arms are extended.

E is an angular brace, consisting of an arm pivoted or jointed at 0 tothe under side of the leaf, the lower end passing through the slot (1,and provided at its extremity with a crosshead, 1, the ends of whichrest and run in the side slots,ff, of the lever O.

The operation is as follows: lVhen the leaf is extended, the arms 0 Dwill be straightened, as shown in Fig. 1, and the brace E will fall ofits own weight, the cross-head 1 running down in the side slots, ff,when, by reason ofits angular position, it will brace the arms and holdthem extended till it is slipped back. This is done by placing thefingers on the under side and grasping the cross-head. The slot Z is toallow full operation of the support when there is a variation in theprojection of the fixed top beyond the frame. If desired, the play maybe allowed at the lower bearing, 0. hen the arms are extended and thebrace lowered, as above described, the hook p strikes over and engageswith the crossbar h, by which means the two arms are hooked together,and any longitudinal strain produced on the arms by raising the outeredge of the leaf or by other means will prevent strain on the hinge ofthe leaf, and will lock the parts securely together.

One great advantage in this device is the connection of the brace E withthe arm 0 by the cross-head r resting in side slots, ff, of the arm, bymeans of which the arm is positively operated in both directions as thebrace is thrown forward and back, the action being thus automatic.

Another advantage consists in the use of the hook p, engaging with thecross-bar 71, for the purposes before described.

This invention is applicable not only to the leaves of tables,sewing-machines, &c., but also to seats, settees, and for similar uses.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. In a table-leaf support, the combination, with the two jointed arms 0D, of the inclined brace E, jointed at one end to the leaf, and providedat the other end with a cross-head, 9', that runs in side slots,ff, ofthe arm 0, as shown and described, and for the purpose specified.

2. In a table-leaf support, the combination of the two jointed arms 0 Dand the inclined brace E, the brace provided with a cross-head l my namein the presence of two subscribing at itscloweg egd, that Druns indsigeslits (13f 13111: witnesses. arm an t e arm provi e Wit a 00 10, thatengages with a cross-bar, h, on arm 0, IRA WVINANS' 5 as shown anddescribed, and for the purpose Witnesses:
